How do I make this situation better?

I went home to visit family 450+ miles. I went to my mom's first and she knew myself and my 15 month old baby were coming and greeted us falling down passing out drunk. I didn't realize at the time that that was what was wrong becuase somehow she masked the alcohol on her breath, and she had hidden all evidence of alcohol. She does have liver disease and has had recent health problems including passing out, and seizures. I called 911 becasue I could not get her to respond to me. She gave consent to go to the hospital and when we got there they confirmed that she had consumed a lot of alcohol and they would get psyche to talk to her once she sobered up. I stayed for a while until I knew her husband was on the way. It was 9:30pm and my baby was getting fussy. I explained to her that I need to take him home to put him to bed and her husband was on the way and I would check in on her by phone. She said "F you!" and now a week later will not speak to me, accept my calls etc. In my opinion if anyone was wrong it was her for putting me in such an awkward position. I do have good memories from when I was a child, but I do not want to be around her in self destruct mode or get blamed for her bad decisons.
